Application filed September 213, 1910, Serial No. 583,7?5.

T all whom it may concern Be it known that l, Ancouu REC/sou, citizen ofthe United States, residing atNcw York city, in the county and State ofNew York, temporarily residing in the city of Pittsburgh, in thecounty'of Allegheny and State of Perms lvania have-invented certam. newand useful Improvements in Jetting Mcthodsof Combustion, .otwhich thefollowing is a specification, reference being hadthercin to theaccompanying drawings. This invention relates to What may be called ajetting or sprayin 1 method of combastion of any gaseous inc whether agas; themixture of gas and air, ora vapor of oil, for examples.

The diflerent forms of apparatus herein shown form the subject-matter ofmy applications Serial Nos. 583,776 and 583,778,both filed Sept. 26,1910.

The objects of this method are to produce intenso heat for variousindustrial purposes, such, for example, as in smelting, reduction,glass-making and cemcnt'burning appa atus; and to improve combustion.

In the accompanying drawings, illustrating the principle of this methodby various forms of apparatus and now known to me, both in relation togas or gaseous fuel and also in relation to oil. vapor, Figure 1 is acentral, vertical section of a form of heating apparatus adapted for theburning of a gas or gaseous mixture according to'thc present method.Fig. 2 is another form oi heater, partially in elevation and partiallyin section, for use in burning; a gas or gaseous fu'cl by the presentmethod.

The apparatus shown is not herein claimed, because it l'ornis thesubject-mutter of my application Serial No. 583,776, of even dateherewith.

char-ring to the accompanying drawings (Fig. 1), 30 is a bunson providedwith the usual air regulator 30 and discharging into a casing 31provided with a centrally i111" perforate wall and a plurality ofsurround inc; perforations 33, the linperforate portion being lndlcatedby 32 and thewall by 34, which extends laterally beyond the casing 31 toiorin a support for casing 35 located thereon and containing acombustion chamthere is mounted a supply pipe 36 having an imperforatelower end preferably opposite the Specification of Letters Eatent.

imperforate portion" of wall and provided with a plurality lateralperforations 37 all around ts annular wall. From the combustion chamberwithin casing 35, exhaust pipes 38 for products of combustion lead tothe casing 39 of vacurun creating and maintaining device ill-providedwith an ex haust-port Casing is provided with a coverili, which mayremoved for igniting the fuel contained in the combustion chamber. The:supply pipe 36 is provided, at its end, exteriorly of casing 35, with ascrew cover 42: having a threaded shank ll that screws into the crossbar43 oil the projecting and ol'the supp pipe. It is obvious that the airregulator may he closedto prevent access of to the ounsen 30, in whichcase its pipe may he used for conveying unmixed. into the chamber 31. Itis also ohvious that the screw cover 42 may be entirely removed to allowfree supply of air or other comlonstion-supporting gas, such as oxygen,for example, to the combustion chamber through the radial perforations37; later 30" and the cover 43 may he regulated to vary the amount ofair admitted past them.

The casing may he ofsny shape, size or contour adapted for any purpose,such as for heating by radiation, or he formed as a member oi? anydesired kind of apparatus for any desired purposs.

When the exhaus fan is in operation and the mixture of gas or gas and alr coming in through the hunsen 30 with the combustion-supporting gassupplied through pipe 36 and entering the coznhiistion chamber throughthe multitude oi? preferably small perforations is ignited, very intenseheat 15 obtained, the products or oomlmstion he ing continuously removedit: i the vicinity of lli'lt3,ilil1lland out of the combustion chamberduring conilnistion. The gaseous fuel entering the chamber of casing 31is jetted upwardly for a considerable distance int the conllmstionchamber, wherein it is intimately mixed with tho combustion-supportinggas which is jetted radially from the tube 36. This crossconnninglingjetted or spray Cl gaseous fuel and combustion-supporting gas c fleets amost thorough mixture thereof, which is greatly favorable and that boththe air regu-' of the i In Fig. 52 I show another form oi apparatususeful in burning gas or gaseous fuel, wherein. the same is jetted intointimate mixture in acombustien chamber with therein jettedcornbustionsupporting gas or air. In this form of apparatus, bunsen 230,

rovided with an air-controller 230, comunieates ttith an enlarged head231 contahiingg-a chamber of considerable capacity as'c nil r ounsen,and in which the air or gas, or

t mixture of air and gas, coming in through the combustion chamber tothe casing 239 of vacuum creating and maintaining device 2d0, the casinghaving an exhaust port 239 The top of the casing of the combustionchamber is shown provided with a form of electricalignition device 2&1for igniting the gaseous fuel as it is jetted or sprayed through theperforations 23d into the combustion chamber, Where it is mixed withair, oxygen or any suitable combustion-supporting gas, that is jettedinto the combustion chamber through the perforations 237 in the lowerend of the central tubular projection 236.

It Will be observed that the jets of the combustible fuel and the jetsof the combustion-supporting gas are at an angle one to the other, sothat a very intimate mixture of the combustion-supporting gas and of thegaseous fuel is'obtained in the combustion chamber, wherein the mixtureis ignited and the products of combustion withdrawn from the combustionchamber through the exhaust pipes 238 by the vacuum producing andmaintaining device, under a rapid move ment thereof, given by a suitablepower connection, not shown.

In all forms of my invention 1 have shown the exhaust pipe leading tothe casing for the vacuum producing and maintaining device as brokenaway, to indicate the fact that in ordinary installations, and,generally speak ng, in all manufacturing installations, the vacuumproducing and maintain ing device is located at a point sul'jstantiallydistant from the combustion chamber.

It will be observed that, in all forms of the apparatus shown, thegaseous fuel and the comlmstion-suppm-tin5; gas (Whether oxygen, forexample, or air is more usual,)

are introduced at a central. point oi" a Wall ipared with thecross-sectional area of of the casing containing the combustion chamber,so that the latter, in efi'ect, extends in all directions laterally ofthe combustion point; except, however, that this exists in a modifieddegree in the apparatus shown in Fig. 2. While What may be called thecentral introduction of the combustion-support ing gas or air is notessential, it is very desirable in many installations, as it secures anincandescent that extends out wardly for a corisiderable distance fromthe point or points at which the combustionsupporting gas is introduced;in other words, it secures a lateral annular expansion oi the flame, andis therefore advantageous tor nmny purposes, especially where a largewall area is to be heated.

In the form of apparatus shown in Fig. 2, the heatingplates, as Well asthe Whole appartus, may be of any size, shape and material desired; andwhat I have said of the advantages of the method as practised byappartus su h as is illustrated in Fig. 1 applies to the operation ofappartus such as illustrated in Fig; 2.

it Will be observed that the gaseous fuel is burned in a partial vacuumcreated in the combustion chamber by the artificial suction, and whilethe fuel is in ahighl'y attenuated vmolecular condition in consequenceof the suction. a

The artificial suction apparatus is operable to secure a uniform,continuous suction. I The Word artificial is used in this specificationin contradistinction to natural draft means. 1 i

W hat I claim is:-

1. The method of combustion which consists in, forming a partial vacuumat the place of combustion, drawing air and gas thereto in a rarefiedcondition in separate jets, mixing the same and then burning therarefied mixture. I

2, The method of combustion which consists in forming a partial vacuumat the place of combustion, causing air and gas to be rarefied, drawingair and gas in separate jets, mixing the same together at the place ofcombustion, burning the said mixture in its rarefied state and forciblywithdrawing the products of combustion.

3. The method of combustion which consists in simultaneously creatingand maintaining a partial vacuum at the place of combustion, crossjetting gases at an angle to each other, mixing and sustaining the gasesin a rarefied state, mining the mixture and forcibly removing theproducts of combustion.

The method of combustion which consists in simultaneously producing apartial umum: at the place of combustion, drawing a jet ol mixed air andgas and a jet of air llicz'otu at angles to each other in a rarefied
